BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of lavender,botanically known as Lavandula stoechas, and hereinafter referred to bythe variety name ‘KLELV15115’. ‘KLELV15115’ originated from across-pollination conducted in November 2008 in Cobbitty, New SouthWales, Australia between the proprietary female lavender variety ‘LS901’(unpatented), and the proprietary male lavender variety ‘LS903’(unpatented).

The seeds from the cross were sown and plants were grown for evaluation,where an individual plant designated ‘KLELV15115’ was selected from thegroup of plants in Cobbitty, New South Wales, Australia in September2009.

In January 2010, ‘KLELV15115’ was first vegetatively propagated by stemcuttings in Cobbitty, NSW, Australia. ‘KLELV15115’ was found toreproduce true to type in successive generations of asexual propagationvia vegetative stem cuttings.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Cobbitty, New South Wales, Australia.

-   -   1. Dark purple terminal bracts; and    -   2. Very early flowering.

DESCRIPTION OF THE PHOTOGRAPH

This new lavender plant is illustrated by the accompanying photographwhich shows the plant's foliage and flowers. The photograph is of a 5month-old plant grown in a greenhouse in Stuttgart, Germany in October2015. The colors shown are as true as can be reasonably obtained byconventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘KLELV15115’. The data which define thesecharacteristics were collected from asexual reproductions carried out inCobbitty, New South Wales, Australia. Data was collected onfour-month-old plants grown in a greenhouse in Cobbitty, New SouthWales, Australia in November 2016. Color references are to The R.H.S.Colour Chart of The Royal Horticultural Society of London (R.H.S.),5^(th) edition (2007).
